The demand function for a certain item is

x=(p+2)9e−px=(p+2)9e−p

Use interval notation to indicate the range of prices corresponding to elastic, inelastic, and unitary

NOTE: When using interval notation in WeBWorK, remember that:
You use 'I' for ∞∞ and '-I' for −∞−∞.
And use 'U' for the union symbol.
a) The range of prices for elastic is

b) The range of prices for inelastic is

a) The prices for unitary is
